I have this issues when I bought my x51 r2  where I cant change colors on side of the panel. It only allow me to a red color. So I just put a red theme and thinking no biggie if I cant change colors. And after a month when I decided to upgrade my gpu and open up the x51 I notice the cable that lits up the system is loose so I simply reattach the cable that connects to the panel. After I turn on my rig all the lights are working. Try to open up your x51 maybe the wire is loose and try to reattach..

So that means your x51 is working now ?..

This happened to me too. When I first got the Area 51, all lights were working fine, then after I adjusted the position of PC, left side LED wasn't lit up.

So I tried to open the panel, but when I grabbed the bottom of PC, the LED came back on.

I think some of X51 came with loose LED connection cable.

Yes

good to hear..

Hi guys. Thanks for the tips.

I've finished putting my PC back together and having tested the lights for a loose connection, the lights still only glow white.

Bryson,

Thanks so much for your help.

I didn't realise there was another connection to the motherboard. Opened the case again, and had the exact problem you described.

Thanks to everyone for their help.
